CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application No. 62/147521, filed on Apr. 14, 2015, which is hereby incorporated by reference in its entirety for all purposes.

BACKGROUND

1. Technical Field

The current subject matter is directed to receptacles, such as buckets, with shields and labels to convey information.

2. Description of the Related Art

Buckets have become a popular medium of transporting goods. There are different labeling mechanisms and lids available today. However, bucket labels are prone to scratch and tear, and are not durable, especially during packaging, shipping, and storing.

SUMMARY

Therefore, it is important for bucket labels to be adequately protected to ensure proper conveyance of information to the user. Furthermore, having labels and shields that protrude from the bucket may also hinder from efficient stacking or nesting of the buckets. Therefore, there is a need to have a shield and label while also providing for ease of nesting and de-nesting of the buckets.

Nested buckets often times create a vacuum or friction in between the buckets that make separating the nested buckets difficult. This makes nesting and de-nesting more cumbersome, requiring more effort and time, and may even limit the number of buckets one could nest because of the difficulty of de-nesting buckets at a high height. Therefore, it is important to identify ways to reduce the vacuum or friction.

Furthermore, one of the challenges to transporting certain goods in buckets is the lack of proper environments for storing and transporting these goods for lengths of time. For example, certain types of goods perish much faster if certain types of gasses coincide with the goods or if the headspace has not been flushed. Therefore, there is a need for a bucket that provides such an environment.

Some embodiments of the present disclosure provide a bucket including a shield with a label or graphics. Additionally, the label may be separate from, in between, or combined as one piece with the bucket and/or shield. The shield, label, and bucket may be manufactured, placed, and/or fastened in a variety of ways, and composed of a variety of different materials. Information on the label can include, for example, sports team information, company information, information about the content of the receptacle and the like. The bucket may have stacked lugs for ease of de-nesting.

Some embodiments of the present disclosure provide a bucket including a lid. The lid may help store certain types of goods. A septum or receptacle may be molded into the lid to allow for injection of inert gases or flushing headspace. Additionally, the bucket may have sufficient strength so that the lid may serve as a seat for sitting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

It should be understood that the present disclosure generally relates to a bucket. The bucket can be a bucket of standard size, such as a 5 gallon bucket that is 11.91″ dia.×14.50″ high×10.33″ dia with a wall thickness of 0.075″ +/−0.005″, where the diameter is different at the top and bottom of the bucket creating a draw. The wall thickness may also be different, ranging from 30 to 50 mils. The bucket may also be a 5 gallon bucket that is 14.5″ in height and 13″ in width, and the inside of the bucket is 13″ in depth and 12″ in diameter. However, any sized bucket, standard or non-standard sized, is appreciated. Furthermore, any structure (for example, a container, crate, bottle) that may provide for storage and receipt of a fluid, solid, or other material which a user wishes to store or transport has been contemplated. The present disclosure is in no way limited to the embodiment disclosed herein. However, for ease of understanding and to provide at least one preferred exemplary embodiment, a bucket system is described. Furthermore, although the embodiments disclose storing liquids in the bucket, it is understood that the present disclosure is not limited to the storage of liquids but may be utilized with any material to be stored.

Turning now to the Figures where like numbers represent like elements, FIGS. 1-8 illustrate several views of the bucket with the shield. FIG. 1A is a first front perspective view of a bucket with a shield according to some embodiments. FIG. 1B is a second front perspective view of the bucket illustrating the shield detached from the bucket according to some embodiments. FIG. 2 is a third front perspective view of a bucket without the shield according to some embodiments. FIG. 3 is a front view of the bucket with the shield according to some embodiments. FIG. 4 is a right view of the bucket with the shield according to some embodiments. FIG. 5 is a back view of the bucket according to some embodiments. FIG. 6 is a left view of the bucket with the shield according to some embodiments. FIG. 7 is a top view of the bucket according to some embodiments. FIG. 8 is a bottom view of the bucket according to some embodiments.

As illustrated in FIG. 1A, the bucket 100 may have at least a bottom portion 102 which may be integrally attached to at least a side wall portion 104. FIG. 1A illustrates the side wall portion 104 to be cylindrical in shape. However, it is appreciated by those of ordinary skill in the art, the side wall portion 104 may have a plurality of different structures including triangular, rectangular, trapezoidal, square and the like. Additionally, with the plurality of different shapes and sizes of the bucket 100, the side wall portion 104 may have a plurality of sides (not shown). The side wall portion 104 may vary depending on the size and shape of the bucket 100 structure.

In FIG. 1A, the side wall portion 104 takes up the entire area of the bottom portion 102 of the bucket 100. The side wall portion 104, in the embodiment of FIG. 1A, represents the largest viewing surface to the individual.

A shield 108 may be placed on the side wall portion 104 of the bucket 100. The label 110 may be placed behind the shield 108. However, it is recognized that the shield 108 and the label 110 may be placed in other areas of the bucket 100. The shield 108 may take up a substantial portion of the side wall portion 104, or may take a smaller portion. The label 110 may be placed on the inside of the shield 108 or the outside of the shield 108.

The shield 108 may be completely clear or partially clear. Thus, the label 110 can be seen through the shield 108. This allows for significant label protection, improves visualization of the conveyance of information, and promotes better utility of a bucket 100 while maintaining the aesthetic and mechanical integrity of the bucket 100.

The side wall portion 104 may also be integrally attached to a top area 106. The top area 106 may contain an opening for allowing an individual to place liquids, solids, or other items for storage inside the bucket 100. It is recognized that there may not be an opening, or the opening may be located in a different area besides the top area 106. Furthermore, the opening can be as wide as the diameter or the width of the side wall portion 104, or may be a different width or diameter. Furthermore, the opening may alternatively come together in a flask like configuration.

FIG. 1B shows the shield 108 detached from the label 110. However, it is recognized that the shield 108 and label 110 may be integrated together. Furthermore, the shield 108 is shown to be generally rectangular in shape, but it is understood that the shape can take on other shapes and forms. The label 110 may be construed from any plurality of materials, including paper, wood, metals, plastic, wax, other types of substrates, and the like. The label 110 may, but is not required to be, generally malleable to be affixed to a plurality of different sized and shaped buckets 100. In the example of FIG. 1B, the label 110 has similar dimensions to the shield 108. The label 110 may be 11¾″ in width and 9½″ in height. However, it is recognized that the label 110 may be smaller than the shield 108, or that label 110 is bigger than the shield 108 and the shield 108 only protects a portion of the label 110.

The shield 108 may attach to the bucket 100 in a variety of different ways. The shield 108 can be a “snap” fit or in some other method of attaching the shield 108 onto the bucket 100. The shield 108 can also be fastened utilizing metal or plastic rivets, or threaded fasteners. The shield 108 may also be secured in a mechanical fashion, such as integrated in the injection mold. The shield 108 may also be sonic welded or chemically bonded to the bucket 100. Sonic welding is a technique whereby high-frequency acoustic vibration is applied to pieces held together under pressure to create a solid-state weld. This type of technique is effective on plastics, but can be used on other types of materials. The shield 108 may also be attached in other methods, such as heated, thermal welding, or using thermal adhesives. The shield 108 may be preformed in a curvature pattern or may be flexible.

FIG. 1C illustrates the label 110 including indicia 112. In the example of FIG. 1C, the indicia 112 displays a number, a baseball, and a name. However, the label 110 may include other information. For instance, the label 110 may include information on the contents of the bucket 100, a corporation's brand, source and destination information, advertisement, and any other information that may be useful for the user or supplier of the bucket 100. For example the label 110 can contain a Material Safety Data Sheet (referred to herein after as “MSDS”) that contains information to provide both workers and emergency personnel with proper procedures for handling, storing, and working with a particular substance. MSDS includes information such as physical data (melting point, boiling point, flash point etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, spill/leak procedures, and more. MSDS is critical for helping prevent workplace exposure and accidents. Allowing for these types of labels can ensure faster and more accurate delivery, storage, and otherwise use of the bucket 100. Furthermore, advertisement, placing corporation's brand, and other information that can be indicia 112 can generate income or have other benefits such as for marketing purposes.

In FIG. 1C, this example shows a bucket 100 used for recreational purposes, storing sporting equipment such as baseballs and team information (e.g., logo) can be displayed under the shield 108 to identify such equipment as belong to such team. In this example, the label 110 shows a picture of a number “22”, a team logo that includes a picture of a baseball, and a team name “Johnson.” For industrial purposes, another example may be a bucket 100 storing nails and the label 110 containing content information such as nail size and length.

In some embodiments, the shield 108 is optional. The label 110 may be placed in an indent in the bucket 100 and can be protected by the outer surface of the side wall portion 104 to prevent scuffing or damaging during bucket nesting and stacking.

The shield 108 may be manufactured in a variety of different ways. For example, the shield 108 can be injection molded or thermoformed utilizing clear impact and/or scratch resistant materials. Some examples include Polypropylene, crystal styrene, polycarbonate, acrylics, polylactic acid (PLA), and Polyethylene terephthalate (PET).

The bucket 100 can be made of a variety of different materials and from different processes. For example, the bucket 100 can be made from one or more of: recycled Polypropylene feedstocks, clarified polypropylene, impact resistant modified polypropylene (e.g., synthetic rubber, metalecines, EVA, elastomers, etc.), plant-based polymers, thermal plastics, and high density polyethylene (HDPE) for low temperature impact performance. HDPE has the advantage of being inert and therefore compatible with a variety of compounds. Thus, testing of compatibility with HDPE may be reduced or avoided. HDPE is also reasonably priced.

The bucket 100 can be made by co-injection technology to incorporate recycle feedstock as a multi-layer structure. Co-injection technology is where two or more individual melt streams unite to make a single article or material. The co-injection technology can be used to apply gas barrier materials in a multi-layer composition. The bucket 100 can also be produced by over molding, which is an injection molding process where one material is molded onto a second material.

A variety of surface treatments can be applied to the surface of the bucket 100. For example, one or more surfaces of the bucket 100 can be plasma treated to enhance gas barrier properties.

When referring to the surfaces, it may be one or more surfaces of the interior of the bucket, one or more surfaces of the exterior of the bucket, or may be a multi-layer where there is a material that serves the treatment purposes.

Further, one or more surfaces of the bucket 100 can be treated or coated with gas barrier materials such as EVOH, PHAE, MXD-6 nylon, LCP, LCP (liquid crystal polymers), blends of known gas barrier materials, plasma coating, and thermoplastic or thermoset coatings. Gas barrier properties are advantageous for food and oxygen sensitive products. For example, buckets that can hold five gallons of food products that are oxygen sensitive can be very useful when shipping to restaurants in volume. The surfaces treated or coated with gas barrier materials may be plasma treated or coated with thermoplastics (Acrylics) or thermosets to enhance gas barrier properties. Thermosets may include highly reacted expoxys or other food contact materials.

The process of overmolding may also be applied where there may be more than one material. Overmolding is known generally as an injection molding process where one material is molded onto a second material. In overmolding, the second material may be an existing bucket which could serve as a blank or preform. Alternatively, the second material could be preformed into a bucket and therefore be a preform or blank. Advantages of some embodiments incorporating overmolding are the reduction of costs of having a cheaper material and a more expensive material. For example, the more expensive material may be gas impermeable and thus may need less of it if overmolding was used. Applying this to the gas barriers (although not limited to this application), multi-layer arrangement allow for the transport of perishable items in buckets that are generally not purposed for perishable items. Although rice, wheat, and beans have been transported traditionally, other more-oxygen-sensitive goods are generally not transported using these industrial sized buckets.

The shield 108 can also be made by at least a portion of clarified polypropylene, which would make the bucket 100 at least partially clear, or see-through, or any of the materials stated for the bucket 100. The bucket and shield can be made of Clarified Polypropylele for a “see through” recycleable combination. FDACPP can be used for food contact applications. Include PE base resins for low temperature impact resistance.

As illustrated in FIG. 7 (top view of the bucket 100), the side wall portion 104 may have an outer side 702 and an inner side 704. The outer side 702 may come in contact with a label 110 which may be applied to the outer side 702 of the side wall portion 104. In some embodiments, the label 110 can be separate from the shield 108 and sandwiched between the outer side 702 and the shield 108, where the label 110 can be inserted into a pocket formed by the recess between the bucket 100 and the shield 108. The shield 108 may protrude from the outer side 702 of the bucket 100 beyond the diameter of the housing, while in other cases, the outer side 702 may be recessed so that the shield 108 is flush or recessed with other portions of the bucket 100. Often times, buckets have a standardized thickness. For example, some buckets have a 30-50 mil thickness (about 0.76 mm-1.27 mm). Some regular card stock paper can be of a certain standardized thickness as well (some about 0.254 mm thick). The shield has to be thick enough to protect the label. Thus for a bucket with 0.76 mm thickness containing card stock paper and a shield that is flush with the diameter of the bucket, the shield can be has to be of a thin thickness, such as between 0.20-0.40 mm, leaving enough thickness for the recessed plastic portion of the bucket behind the label and the shield.

In some embodiments, the label 110 may be applied during manufacturing, such as injection molding, directly onto the shield 108 or directly onto the outer side 702. The label 110 may be applied during injection molding using a technique called in mold labeling, where printed plastic sleeves may be inserted via robot and the melt is in injected under the label 110. Graphics may be predetermined on the sleeve. The label 110 may be applied onto an indent of the outer side 702 and the bucket 100 so as to protect the label 110 from scuffing or damage during bucket nesting or stacking, and may or may not have a shield.

FIG. 9 is a third front perspective view of the bucket 100 with stacking lugs 902 according to some embodiments. The bucket 100 may include stacking lugs 902 for ease of de-nesting. Buckets are generally nested and are often times hard to separate. However, the lugs 902 provide an air gap that reduces vacuum or friction when the buckets are pulled apart. The vacuum created by the inner pulling can be very strong. The stacking lugs create an airspace that prevents the vacuum. Although FIG. 9 shows three stacking lugs, there can be more or less, can be placed in different areas of the bucket 100 and can be of different shapes and sizes.

FIG. 10 is a forth front perspective view of the bucket 100 showing a shield 108 with a lid 1002 disposed thereon according to some embodiments. FIG. 11 is a fifth front perspective view of a bucket 100 without the shield 108 with the lid 1002 disposed thereon according to some embodiments. FIG. 12 is a front view of the bucket 100 with the shield 108 and with the lid 1002 disposed thereon according to some embodiments. FIG. 13 is a right view of the bucket 100 with the shield 108 and with the lid 1002 disposed thereon according to some embodiments. FIG. 14 is a left view of the bucket 100 with the shield 108 and with the lid 1002 disposed thereon according to some embodiments. FIG. 15 is a back view of the bucket 100 with the lid 1002 disposed thereon according to some embodiments. FIG. 16 is a top view of the bucket 100 with the lid 1002 disposed thereon according to some embodiments.

As illustrated in FIG. 10, the bucket 100 may include a lid 1002. In FIG. 10, the lid 1002 has an outer edge and an inner edge where the inner edge is connected to the side wall portion 104 of the bucket 100. However, other designs of the lid 1002 in relation to the bucket 100 are appreciated. For example, the outer circumference of the lid 1002 may be the same as the inner circumference of the top area 106 of the bucket 100. The lid 1002 may be snap fit, fastened, or attached to the bucket 100, and configured to allow the lid to be detached from the bucket 100. The lid 1002 may be a completely separate piece from the bucket 100 or may be a part of the bucket 100 that can be moved in a way to create a closing member for the bucket 100. The lid may be any closing member of the opening in the bucket 100.

FIG. 17 is a front view of the lid with a septum and membrane according to some embodiments. The lid 1002 may be configured such that the bucket 100 can be used for packaging dry goods as well as liquids and food products. A septum 1702 or receptacle may be installed or molded into the lid 1002 for the purposes of injecting inert gases or flushing the headspace. A septum 1702 may include a means to insert a needle or probe to inject or extract gas or liquid from containers that are at atmospheric pressure. The combination of septums and valves allow the headspace to be flushed with, for example, nitrogen where the absence of oxygen is required. Injecting a drop or more of liquid nitrogen into the bucket 100 may create a nitrogen rich environment with positive pressure. This is advantageous because only a septum 1702 is required and not gas flow to flush the headspace.

Furthermore, a membrane 1704 is shown in FIG. 17. This membrane may be used as a relief valve which controls or limits the pressure in the bucket 100. Pressure may be relieved allowing the pressurized substance to flow from an auxiliary passage out of the bucket. The relief valve may have a predetermined set pressure to protect pressure vessels and other equipment from being subject to excess pressure.
